Hello, everyone
I am using CESM2.1.4 and BHIST to do some smulations. In our study, we need to divide the dry deposition into turbulent deposition and gravitational deposition. But I see the *DDF* is a sum of turbulent deposition and gravitational deposition. The model uses MAM4, and for a1, a2, a4 and c1, c2, c4, I think they are mainly governed by turbulent deposition. But for a3 and c3, I am confused because its range is too wide.
So I want to know how to get the ratio of the diameter less than 5 µm. I will consider this part also governed by turbulent deposition, other greater than 5 µm part governed by gravitational deposition.
